As the CEO and founder of Apple, Jobs hardly talked about his personal life in public. Here are some specific things.

1:Early life and childhood  Jobs was born in San Francisco on February 24, 1955. He was adopted(收养) shortly after his birth by a couple(夫妇) named Clara and Paul Jobs. He grew up in California. Later in life, Jobs discovered who were his birth parents. However, Jobs only had some communication with his birth mother.

2: College dropout After leaving high school, Jobs entered Reed College in 1972. Jobs stayed there for only one semester, because his parents couldn’t afford his education.

3: An important date Jobs actually missed a meeting because of his first date(约会)with his wife, Lauren Powell. He said, “I was in the parking lot (停车场)with the key in the car, and I thought to myself, ‘If this is my last night on Earth, would I rather spend it at a business meeting or with this woman? ’ I ran across the parking lot, and asked her if she’d have dinner with me. She said yes, we walked into town and we’ve been together ever since. ”

4:His sister is a famous author Later in his life, Jobs met up with his biological sister Mona Simpson, the famous author of Anywhere But Here.

5:His first daughter When he was 23, Jobs and his high school girlfriend Brennan had a daughter, Lisa Brennan Jobs. He and Brennan never married. Jobs paid for his first daughter’s education at Harvard. She graduated in 2000 and now works as a magazine writer.

    6:His fortune As the CEO of Apple, Jobs only took $1 a year, but Jobs leaves behind a vast fortune. In 2011, with $8. 3 billion, he was the 110th richest person in the world, according to Forbes.

阅读下表信息后判断:

早在1931年9月18日,日军自导自演“事变”,在欧洲战端尚未开启之时,就掀起侵略中国的序幕。在相当长的时间里,中国独力支撑着东方战场的局面。1937年7月7日,中国的全民族抗战,开辟了世界反法西斯的第一个大规模战场。正如***指出的,中华民族的奋起抵抗,使中国“紧密地与世界连成一体”,“我们的敌人是世界性的敌人,中国的抗战是世界性的抗战”。旷日持久的中国抗战,不仅支持了英美继续贯彻其“先欧后亚”战略,而且是东亚和太平洋战场能够转入战略反攻的重要原因。美国总统罗斯福指出,不断加强的“中国的壮丽的防御战”是阻止希特勒征服世界的重要因素之一。斯大林感慨“中国人民及其解放军的斗争,大大地便利了击溃日本侵略力量的事业”。英国首相丘吉尔则承认,“中国一崩溃,至少会使日军15个师、也许会有20个师腾出手来……”   

日本军国主义残暴的铁蹄践踏之下,中国不但没有崩溃,反而愈战愈勇,以3500多万人伤亡的巨大牺牲,牵制并消灭了日军大部分主力。太平洋战争爆发时,日本陆军总兵力的七成仍深陷于中国战场。中国的顽强抵御,推迟了德、意、日轴心国的军事联合,使日本在欧战爆发时未能在军事上配合德国;中国艰苦卓绝的努力,阻碍了日军的北进图谋,消除了苏联卫国战争的后顾之忧;中国排除万难的相持和远征,打乱了日军的南下布局,避免了法西斯势力的合流。
